When refreshing fields (ajax refresh) the tab index of the fields is lost, and after studying the details of the issue on the page, we concluded that the tabindex values go through absurd variations, ignoring completely the order we settled on the interface (through extended properties) in the development software: Outsystems.

After several tests, we found further issues, beyond the refreshing forms issue. There are still other problems involving losing the count of the tabindex. For example, the order of the tab index, get completely random after hit the 16th index.
